Gold parting - Wikipedia

Separation of gold from silver was not practised in antiquity prior to the Lydian Period (12th century BC to 546BC). Material from Sardis (in modern Turkey) is evidence of the earliest use of gold and silver parting in the 6th century. Literary sources and the lack of physical evidence suggest that gold-silver parting was not practised before the mid first millennium BC.
